2. a student carries a glass cube whose length of the edge (l) is 4.425 ��. the density of the glass is 3.755 g/cm3 . she drops the cube, and a piece having a mass of 19.40 g breaks off. to repair the cube, student adds plastic having a density of 2.355 g/cm3 and reshapes the cube to its original shape and size. (a) what is the volume of the plastic part? (b) what is the volume of the composite object? (c) calculate the volume of the glass. (e) calculate the mass of the glass. (f) what is the mass of the composite cube? (g) calculate the density of the new composite cube.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
